Geonic road alignment format

Read and writes Geonic horizontal and vertical geometries. Vertical geometry file is read automatically, if a PG-file with same name is found in same directory.

In reading converter checks file row length and if the length is more than standard 74 characters, reads file automatically using below mentioned GtFlag special setting Allow wider fields.

Special settings

There are some special settings related to this converter.

VerticalArcSign

Changing arc sign when reading vertical geometry. Arc radius is multiplied by value.

GtFlag

1 Allow wider fields - Reads space separated fields instead of standard fixed size fields and writes files with 12 character field widths.
